Pappy J is wrong on topic but correct about fuscelage index marks. They are more commonly used in heavy maintenance when the aircraft needs to be jacked and shored prior to removal of too many skins. The aircraft is measured with survey equiptment then checked again after the structural work is complete. MDC products use a large button head rivit.
